This document provides instructions for installing Python and IPython on different Linux distributions like Debian, Fedora, Gentoo, and Ubuntu. It also demonstrates various Python concepts like declaring variables, whitespace, comments, strings, input/output, conditionals, functions, lists, dictionaries, loops, and classes.
![function
Def function_name (argument[, argument]):
#Do](https://image.slidesharecdn.com/python-140731062436-phpapp01/85/Python-10-320.jpg)
![Lists
EX:
numbers = [5, 6, 7, 8]
numbers[0] = 5
len(numbers) // 4
numbers[start: end: step]
numbers.append(9)](https://image.slidesharecdn.com/python-140731062436-phpapp01/85/Python-11-320.jpg)
![Dictionaries
EX:
d = {'key1' : 1, 'key2' : 2, 'key3' : 3}
d['key1' ] = 1
d['key4’ ] = 4
d.remove('key3' )](https://image.slidesharecdn.com/python-140731062436-phpapp01/85/Python-12-320.jpg)
大家一起學Python
- 1. 大家一起學python
- 2. 環境安裝 Debian版本的安装命令如下： su – aptitude install ipython python-setuptools Fedora版本的安装命令如下： su – yum install ipython python-setuptools-devel Gentoo版本的安装命令如下： su – emerge ipython Ubuntu版本的安装命令如下： sudo apt-get install ipython python-setuptools
- 3. 從軟體源安裝 來源:https://github.com/ipython/ipython/downloads 解壓縮:tar xzf ipython-<version>.tar.gz 使用git:git clone https://github.com/ipython/ipython.git 進入ipython目錄:cd ipython 安裝指令:sudo setup.py install
- 4. 宣告變數 my_int = 7 my_float = 1.23 my_bool = True my_string = “Hello!”
- 5. Whitespace def spam(): eggs = 12 return eggs print spam() Vim 縮排設定:vim ~/.vimrc set sw=4 set ts=4 filetype indent on autocmd FileType python setlocal et sta sw=4 sts=4 參考: http://linux-wiki.cn/wiki/Vim%E4%BB%A3%E7%A0%81%E7%BC%A9%E8%BF%9B%E8%AE%BE%E7%BD%AE
- 7. String my_string = “Hello” String_len = len(my_string) // 5 my_string.lower() //”hello” my_string. upper() //”HELLO” str(10) // “10” + "Let's not go to %s. 'Tis a silly %s." % (str1, str2)
- 8. 輸入 my_input = int(raw_input(“input message:"))
- 9. Conditionals EX: if answer > 5: return 1 elif answer < 5: return -1 else: return 0
- 10. function Def function_name (argument[, argument]): #Do
- 11. Lists EX: numbers = [5, 6, 7, 8] numbers[0] = 5 len(numbers) // 4 numbers[start: end: step] numbers.append(9)
- 12. Dictionaries EX: d = {'key1' : 1, 'key2' : 2, 'key3' : 3} d['key1' ] = 1 d['key4’ ] = 4 d.remove('key3' )
- 13. Loop EX: while condition: #Do else: # for variable in list_name: for i in range(): # Do #Do
- 14. Class class CLASS_NAME(object): def __init__(self, a1, a2, a3) self.a1 = a1 self.a2 = a2 self.a3 = a3 My_class = CLASS_NAME(a1,a2,a3)
